Description

DETAILED DESCRIPTION OF THE INVENTION A1 Object of the Invention (1) Industrial Field of Application The present invention relates to a support device for an operation pedal in an automobile, and more specifically, to a support device for an operating pedal in a vehicle, and more specifically, to a lower surface of a steering hanger protruding from a dash board of a vehicle body toward a passenger compartment. This invention relates to a pedal bracket that is connected to a dash board and extends toward the passenger compartment, and an operating pedal such as a brake pedal is rotatably supported on a horizontal pedal shaft provided on the pedal bracket.

(2) Conventional Technology Conventionally, in such an operating pedal support device, the pedal bracket is comprised of a ceiling plate that is superposed and bonded to the lower surface of the steering hanger, and a pair of side wall plates that hang down from both left and right ends of the ceiling plate. It was formed into an inverted U-shaped cross section with an open bottom.

(3) Problems to be Solved by the Invention When the lower surface of the pedal bracket is open, there is an advantage that the operating pedal can be easily installed between the side walls of the bracket through the open surface. On the other hand, the side wall plates have low rigidity, and have the disadvantage that they resonate with engine idle link vibrations and easily generate abnormal noise.

The present invention has been made in view of this problem, and uses a steering hanger to increase the rigidity of the pedal bracket, thereby preventing resonance of the pedal bracket to the idle link vibration, and further improving the arrangement of the operation pedal. Is it possible to provide a support device for the operating pedal so that it does not cause any interference? purpose.

f8M of the B6 Invention (1) Means for Solving the Problems In order to achieve the above object, the present invention provides a pedal bracket that extends from a bottom wall plate and both left and right ends of the bottom wall plate and connects the steering wheel to the steering wheel. a pair of side wall plates whose upper ends are fixed to the side wall plates, the supporting shaft is installed between the side wall plates, and a long hole is bored in the bottom wall plate to allow the operation pedal to pass through and rotate. It has different characteristics.

(2) Effects According to the above configuration, the pedal bracket whose upper end is open cooperates with the steering hanger to form a box-shaped structure in cross section, so that the rigidity is significantly enhanced.

Moreover, since the bottom wall plate of the pedal bracket has a long hole that allows the operation pedal to pass through and rotate, it will not interfere with the bottom wall plate (the operation pedal can be inserted between the side walls of the pedal bracket). The operation pedal can be firmly supported by the support shaft supported at both ends by the side wall plates.

(3) Example Hereinafter, an example of the present invention will be explained with reference to the drawings. First, in FIGS. 1 and 2, a passenger compartment 2 of an automobile body
And on the dash board 1 that partitions the engine compartment 3,
A steering hanger 4 protruding toward the vehicle interior 2 and a stiffener 5 located below the steering hanger 4 are welded together.
In addition to the steering wheel 4 and stiffener 5, a brake pedal 6 as an operation pedal to which the present invention is applied;
A pedal bracket 9 that supports the accelerator pedal 7 and the steering column 8 is connected.

As shown in FIGS. 3 to 5, the steering hanger 4 includes an upper plate 10 having an inverted U-shaped cross section with an open lower surface, and a lower plate 11 welded to the upper plate 10 so as to close the open lower surface. It is composed of

Similarly, as shown in FIGS. 3 to 5, the pedal bracket 9 has a cross section U from a bottom wall plate 12 and a pair of side wall plates 13.1'3' rising from both left and right ends of the bottom wall plate 12. formed into a letter shape. As shown in FIGS. 1 and 2, a mounting plate 14 is welded to the front ends of both side wall plates 13 and 13' to connect them, and the mounting plate 14 is attached to the dash board through the stiffener 5. 1 by a plurality of welding bolts 15 and nuts 16.

Further, the upper ends of both side wall plates 13 and 13' are formed with outward flanges 13α and 13α', and these flanges 13α.

13a' is fixed to the lower plate 11 of the steering hanger 4 with a plurality of bolts 11 and weld nuts 18.

As shown in FIGS. 1 and 5, a support shaft 19 made of bolts is installed horizontally between the side wall plates 13 and 13' of the pedal bracket 9, and the support shaft 19 is attached to the brake pedal 6.
The proximal end of the pedal 6 is rotatably supported, and a pair of collars 20, 20 for restraining the axial movement of the pedal 6 are fitted.

The brake pedal 6 has a long hole 21 bored in the bottom wall plate 12.
The elongated hole 21 extends downward through the pedal 6.
It is formed to a size that allows rotation of (・ru.And,
The input rod 2 of the brake booster 22 is attached to the brake pedal 6.
2α is connected so that the brake booster 22 can be actuated by pressing the pedal 6.

A stop switch 23 is mounted on the bottom wall plate 12 to turn on a stop lamp at the rear of the vehicle body in response to depression of the brake pedal 6.

Referring again to FIGS. 1 and 2, a second support shaft 24 is horizontally provided on the outer surface of the right side wall plate 13'. The support shaft 24 has a reinforcing wall 14α rising from the mounting plate 14 at an intermediate portion.
The accelerator pedal T is fixed to the outer end of the support shaft 24.
is rotatably supported. A throttle wire 25 connected to a throttle valve of an engine (not shown) is connected to the accelerator pedal γ.

Further, a steering column 8 is fitted and welded to the rear end of the pedal bracket 9, and a steering shaft (not shown) connected to a steering handle is supported by the column 8.

Next, to explain the operation of this embodiment, the pedal bracket 9 has a bottom wall plate 12 and a pair of left and right side wall plates 13, 1.
3', the top surface is open and the bottom surface is closed.
3' is tied to the steering hanger 4, so
The open upper surface of the pedal bracket 9 is connected to the steering hanger 4.
Closed by. As a result, the pedal bracket 9 is
Since it cooperates with the steering hanger 4 to form a box-shaped structure in cross section, the rigidity is significantly enhanced.

In addition, since the bottom wall plate 12 of the pedal bracket 9 is provided with a long hole 21 that allows the brake pedal 60 to pass through and rotate, the brake pedal 6 can be attached to both side walls without being interfered with by the bottom wall plate 12. It is possible to arrange the brake ring 6 between 13.degree.

In the present invention, if the upper plate 10, lower plate 11, and pedal bracket 9 of the steering hanger 4 are aligned with each other by a common screw member, a strong box-shaped structure can be obtained. It is also effective to omit the lower plate 11 of the hanger 4 and connect the pedal bracket 9 to the upper plate 10.

C1 Effects of the Invention As described above, according to the present invention, the pedal bracket is composed of a bottom wall plate and a pair of side wall plates rising from both left and right ends of the bottom wall plate and having their upper ends fixed to the steering hanger. , the support shaft is installed between the side wall plates, and a long hole is bored in the bottom wall plate to allow the operation pedal to pass through and rotate, so the rigidity of the pedal bracket can be effectively increased by using it as a steering hanger. This prevents the pedal bracket from resonating with the engine's idle link vibrations and causing no abnormal noise.

Moreover, the operating pedal can be firmly supported on the support shaft between the side wall plates without being interfered with by the bottom wall plate of the pedal bracket.
